a) Minimum Duplication and Redundancy of Data
b) High Level of Security
c) Single-user Access only
d) Support ACID Property
Single-user access only is NOT a feature of DBMS.
DBMS systems are designed to handle multiple users accessing and manipulating data simultaneously. This is a core functionality.
Here’s a breakdown of the other options:
- Minimum Duplication and Redundancy of Data: DBMS ensures data integrity by preventing data duplication and redundancy.
- High Level of Security: DBMS provides mechanisms to protect data from unauthorized access.
- Support ACID Property: ACID (Atomicity, Consistency, Isolation, Durability) is a fundamental property of transaction management in DBMS, ensuring data integrity.
Therefore, single-user access only is the outlier and not a feature of DBMS.
